+**Nelm** is a Helm 3 alternative. It is a Kubernetes deployment tool that manages Helm Charts and deploys them to Kubernetes and also is the deployment engine of [werf](https://github.com/werf/werf). It can do (almost) everything that Helm does, but better, and even quite some on top of it. Nelm is based on improved and partially rewritten Helm 3 codebase, to introduce:
 
 * `terraform plan`-like capabilities;
 * replacement of 3-Way Merge with Server-Side Apply;
 * secrets management;
 * advanced resource ordering capabilities;
 * improved resource state/error tracking;
 * continuous printing of logs, events, resource statuses and errors during deploy;
-* fixes for many Helm 3 issues, e.g. ["no matches for kind Deployment in version apps/v1beta1"](https://github.com/helm/helm/issues/7219);
+* lots of fixes for Helm 3 bugs, e.g. ["no matches for kind Deployment in version apps/v1beta1"](https://github.com/helm/helm/issues/7219);
 * ... and more.

 ### Printing logs and events during deploy
 
 During deploy Nelm finds Pods of deployed release resources and periodically prints their container logs. Also, with annotation `werf.io/show-service-messages: "true"` resource events are printed too. Log/event printing can be tuned with annotations.

 ### Release planning
 
 `nelm release plan install` explains exactly what's going to happen in a cluster on the next release. Shows 100% accurate diffs between current and to-be resource versions, utilizing robust dry-run Server-Side Apply instead of client-side trickery.
